Intermec EasyCoder PF2i, PF4i, and PF4i Compact Industrial—Service Manual 65
Chapter 6—Transfer Ribbon Mechanism
6.3 Ribbon Rewind Unit
Description
For logistic reasons, the ribbon rewind unit consists of the same parts as
the ribbon supply unit (see Chapter 6.2) with the exception that there is
no spring clutch.
The ribbon rewind bobbin winds up the used ribbon on its cardboard
core after printing. It is driven via a gearbox by the ribbon motor. A gear
wheel in the gearbox engages the cogs along the rim of the inner part of
the bobbin. The bobbin rotates counterclockwise to wind up the ribbon
during printing or clockwise to allow the ribbon to follow the media when
it is pulled back.
Replacement
• Pry the two legs of the snap-lock in the bobbin apart using a pair of fl at-
tipped screwdrivers. At the same time, pull out the bobbin.
• Remove the hub from the shaft, if necessary.
• If the shaft needs to be removed, use a piece of isolating tape to protect
the shaft from being scratched by the tool.
• Reassemble in reverse order. Take care so the cogs along the rim of the
bobbin engage the gear wheel in the gearbox properly.
